Review: Blue Sadie Headphones

The successor to Blue’s Mo-Fi over-ear headphones, the Sadie updates and refines the unique-looking — and unique-fitting — set of over-ear cans. This pair, which sits above the planar magnetic Ella and below the amp-devoid Lola in Blue’s lineup, is primarily targeted to mobile users (read: just about everybody who listens to music nowadays) relying on their laptops, smartphones, and tablets as the primary source of music, since all these devices lack dedicated amplifiers and thus require external outboard ones to optimally power HiFi headphones. But more than that they feature a Formula One-inspired articulating frame for improving fit in a way an extending band never could. We finally got a chance to test a pair ourselves over the past few weeks so if you’re curious keep on reading.


Sadie may look big in online images but the pair is even bigger in person. Two oversized circumaural earcups press into your head and surround your ears, simultaneously insulating sound while avoiding putting any pressure directly on your ears. The earcups feature a bit of elegant-looking plastic in the form of a shell covering most of the outside, but almost every other visible part on the set is made of metal. That includes the race car-influenced suspension frame. The general frame design is shared with the Mo-Fi, albeit refined, though it’s still got three articulating joints on either side, expanding in width, height, and angle to fit a variety of head shapes and sizes. They do feel quite sturdy thanks to the use of metal but as a consequence this increases overall weight to just over one pound, nearly twice as much as some comparable pairs.

Below the left cup there’s a 3.5mm input for plugging in one of the two included cables, one plain vanilla at nearly 10 feet long and the other at four feet with three buttons and an inline mic in an enclosure that appears to be made of the same dark, anodized metal as most of the frame. The headphone jack input also sports a textured silver ring around it that switches the headphone amp between its three settings: off, on, and on+. More on the nuances of these settings in the sound section. Besides this there’s a MicroUSB input to charge the inbuilt rechargeable battery. The outgoing Mo-Fi had a tension switch; there’s none of this on the Sadie, though we didn’t really miss it. There’s no on switch anywhere either: instead, put the pair on your head and they’ll turn on automatically; take them off to have them shut off. The frame detects the earcups being pulled apart and knows to turn them on, and you’ll know it yourself thanks to a subtle glow coming from behind the Blue logo on either earcup.

Appreciating their almost mechanical black-and-silver aesthetics is more or less up to individual taste. Minimal they’re not but we think we’d be hard pressed to find anyone thinking they didn’t look good, not to mention well-built.


If they weren’t comfortable the suspension frame wouldn’t be doing itself any favors. Fortunately they are, and this despite their size and considerable weight. Thick memory foam padding on both the earcups and headband certainly help dissipate both the weight as well as the clamping pressure of the suspension, which isn’t insignificant considering it needs to be enough to solidly hold these hefty bad boys on your noggin. We definitely wouldn’t say we could forget we’re wearing them, especially when turning your head or making quick movements and feeling the headphones follow suit a fraction of a second later, but the fit feels tailored, and it basically is considering you’ll naturally (and effortlessly) customize both the fit and angle of the earcups every time you put them on. Even during prolonged wear our head and ears remained surprisingly comfortable.


To the good stuff. Inside they’ve got the aforementioned 240mW audiophile amplifier as well as 50mm fiber-reinforced dynamic drivers and a rechargeable battery capacious enough for about 12 hours of playtime. If you don’t want to use the amp, or if the batteries are dead, switch the dial to off. If you do have it on though you’ll be rewarded by an enlarged soundstage that gets loud. In fact we recommend, as Blue does, to not only start at a low volume and crank it up as it’s playing to figure out optimal volume levels and avoid blasting your eardrums accidentally — and same goes when switching between modes, just in case.

While the drivers are the same as on the outgoing Mo-Fi they’re tuned slightly differently. And when compared to headphones with smaller drivers we found the sound really shone when volumes were set a little higher. Our experience suggests that the sound isn’t skewed towards the popular bass-heavy profiles of many other modern headphones like those from Bose and Beats, something we appreciated. Sound was warm, rather crisp and clean, and with perhaps just a very slight skew towards lower frequencies. Overall the sound is natural and powerful without tiring out your ears.

If you need more bass switch them to on+ mode. This boosted bass specifically while leaving treble and mids largely unaffected, but still not to Beats levels so if you’re really craving over-the-top booming percussion you’ll need to use a software-level equalizer on your device to address that.

All of this isn’t to say that they don’t sound good with the amp off. On the contrary, it results in sound that’s not dissimilar from when it’s on, if you crank the levels up appropriately considering the amp does give it a fair volume boost. Turning it on does extend the range slightly but noticeably, and our preferred general listening mode for as variety of tracks was not on+ nor off but rather on. Tastes vary, though, and different tracks can easily sound subjectively better in one mode or another, most often either on or on+. It should also be noted that while they’re devoid of active sound cancellation the foam and closed-back (and likely higher-than-average listening volumes you’re likely to set) block out ambient noises fairly well.


To wrap up, the Sadie delivered when it came to sound with the amp both off and on, likely to be appreciated by most music buffs looking for a mid-to-high-end pair of over-ear headphones. Its solid sound is less likely to be a point of contention compared to their size, weight, price, and design. They’re certainly distinctive in appearance and fit us quite comfortably despite the above but listeners perfectly content with traditional extensible headphone bands and cheap-feeling but lightweight plastic might question the necessity of the overbuilt articulating frame that detracts from portability. Others, who’ve rarely if ever found a perfect fit that stays comfortably in place over long stretches of listening, are bound to absolutely love it.
